What is a Slot?

A slot is a narrow opening or groove in something. For example, letters go through the mail slot at the post office. A slot can also refer to a position on a board game where you place your chips, or in computer software, a place where information is stored.

In a casino, slot is the name of a machine that pays out winning combinations of symbols. The machine’s pay table shows how many coins (or credits) a player will win for each combination of symbols and where those symbols must be positioned on the machine’s payline for the bettor to receive the payout. Some older reel machines list the pay tables on the face of the machine, and video slot machines display them when a player presses a “pay table” button or icon.

A t-slot table is an extension of the work area on a universal testing machine that provides a convenient way to secure components and structures during tensile, compression, and flexural tests. Commercially available T-slot nuts are slid into the inverted T-slot of the table and bolted to the machine frame using threaded rods, studs, or bolts.
